A rectangular tin 20 cm long and 12 cm wide contains 1680 cm³ of flour. what is the depth of flour in the tin if it is spread evenly.
Answers
Given:
✰ Length of a rectangular tin = 20 cm
✰ Breadth of a rectangular tin = 12 cm
✰ Volume of flour = 1680 cm³
To find:
✠ The depth of flour in the tin.
Solution:
Let's understand the concept first! As we are provided with the length and breadth of the rectangular tin and the volume of a floor, which is equal to the volume of the rectangular tin. So we will use the volume of a rectangle, putting the values in the formula and then doing the required calculations, we will find the depth of the floor or we can say the depth of a rectangular tin.
Let's find out...✧
✭ Volume of rectangle = l × b × d ✭
Here,
- l is the length of a rectangular tin.
- b is the width of a rectangular tin.
- d is the depth of a rectangular tin.
Putting the values in the formula, we have:
➤ 1680 = 20 × 12 × d
➤ d = 1680/(20 × 12)
➤ d = 168/(2 × 12)
➤ d = 84/12
➤ d = 42 cm
∴ The depth of flour in the tin = 42 cm
More Formulae:
- Perimeter of rectangle = 2( length + breadth )
- Area of rectangle = length × breadth
- Length of the diagonal of rectangle = √(a² + b²)
